  1. 1. Approach for frequency response-calibration for microphone arrays

    University essay from KTH/Hälsoinformatik och logistik

    Author : Jacob Drotz; [2023]
    Keywords : microphone array; frequency response; calibration; sine sweep; inverse filter; digital signal processing DSP ; convolution; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; acoustic measurements; audio engineering; mikrofonarray; frekvenssvar; kalibrering; sinussvep; inverterat filter; digital signalbehandling; faltning; Fast Fourier Transform FFT ; Discrete Fourier Transform DFT ; akustiska mätningar; ljudteknik;

    Abstract : Matched frequency responses are a fundamental starting point for a variety ofimplementations for microphone arrays. In this report, two methods for frequencyresponse-calibration of a pre-assembled microphone array are presented andevaluated. READ MORE

  2. 2. Design of auxiliary communication for audio between computers and DSPs : Programming and optimization of computational resources

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Eriksson Janze Oscar; [2023]
    Keywords : DSP; Audio-communication; Auxiliary; AUX; phone connector; USB-audio; STM32; ADC; AD-converter; filterbank; hearing aid; signalprocessor; ljudkommunikation; ljudkabel; AUX; USB-ljud; STM32; hjälpmedel; ADC; analog-till-digital-omvandlare;

    Abstract : This thesis report is about designing a prototype and establishing audio communication between a computer and Digital Signal Processor (DSP) using two preamp circuits using both auxiliary and USB connection. The paper gives the reader an overview on how audio is transmitted from a computer, through the system and to the desired output. READ MORE

  3. 3. Intercorrelation between sound design, binaural and non-binaural audio systems : Effects on general vertical localization precision and reaction time in a non-visual directional choice task 3D game

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Author : David Baker; [2022]
    Keywords : Spatialization; binaural synthesis; HRTF; stereo; 3D audio; videogames; ASC; Auditory spatial schema; Head related transfer function;

    Abstract : Spatialization of audio in the vertical plane has historically been limited. Instead, sound designers have used basic DSP to create pseudo height effects to explain the positions of corresponding objects. In recent years, binaural synthesis has become more widespread following an increase in the use of software rendering methods. READ MORE

  4. 4. A Hardware Accelerated Low Power DSP for Recurrent Neural Networks

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Allan Andersen; Ilayda Yaman; [2020]
    Keywords : Digital Signal Processor; Hardware Accelerator; Machine Learning; Deep Learning; Recurrent Neural Networks; Gated Recurrent Unit; Technology and Engineering;

    Abstract : Recurrent neural networks (RNNs) have become a dominating player for processing of sequential data such as speech and audio. The reason for this, is the high accuracy that can be achieved with the more complex variants, such as the gated recurrent unit (GRU). READ MORE

  5. 5. Automatic audio sample finder for music creation : Melodic audio segmentation using DSP and machine learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Pituk; [2019]
    Keywords : ;

    Abstract : In the field of audio signal processing, there have always been attempts to cre- ate tools which help musicians by automating processes for music creation or analysis, and the electronic music industry is still playing an important role in the combination of software engineering and music.  In the age of sample based synthesizers and sequencers, creating and using high quality and unique audio sample packages is a crucial part for composing songs.
